{
    public class ColumnsExample
    {
        private readonly SchoolContext _context;

        public ColumnsExample(SchoolContext dataContext)
        {
            // Sets the data context
            _context = dataContext;
        }

        public void Example()
        {
            // Instantiates datastore with datawindow: d_department
            var datastore = new DataStore("d_department", _context);

            datastore.Retrieve();
			
			// Gets the properties of the Columns.
            var columnMetas = datastore.DwMeta.Columns;
            Console.WriteLine("Columns Count: {0}", columnMetas.Count);

            // Gets the zero-based ID of the column.  
            for (int i = 0; i < columnMetas.Count; i++)
            {
                Console.WriteLine("Column Name: {0}; ID: {1}",
                    columnMetas[i].Name, columnMetas[i].ID);
            }

            // Gets the appearance and behavior properties of the first column.
            var dwDddw = columnMetas[0].Dddw;
            Console.WriteLine("HScrollBar: {0}", dwDddw.HScrollBar);
            Console.WriteLine("VScrollBar: {0}", dwDddw.VScrollBar);
